In this 4K Video Downloader not working guide, we'll explain the different errors you might see while downloading videos and also address app crash issues on your desktop and Android devices.

Part 1. Why Is 4K Video Downloader Not Working: 4 Common Errors

You can download the 4K Video Downloader app on your computer or Android device and use it to download videos or audio from different streaming platforms. These include YouTube, TikTok, Instagram, Facebook, DailyMotion, Vimeo, Twitch, SoundCloud, Bilibili, Flickr, Tumblr, Naver TV, Niconico, and even streams from YouTube Gaming.

It's a great product. You can simply paste the link to your favorite video, and it will download it for you. However, many users face frequent errors while using the 4K Video Downloader platform.

These errors can be faulting to activate the license key, videos not downloading, downloadable links not parsing, or the app frequently crashing on your PC or Android device.

Part 2. Why Is 4K Video Downloader Not Activated?

There are many reasons why you might be facing 4K Video Downloader license key activation issues. Below, we will discuss each one and provide a solution.

If you've paid for the license key, but you did not receive the key number along with the activation instructions in your email, and it's been a while:

1. Make sure to check the email you use to buy the license key.
2. Check your spam folder because email providers often mark these emails as spam.
3. Contact 4K Video Downloader support and provide them with your purchase email and the order ID. They will sort out the issue.

You may also have lost the license key by accidentally deleting the email. In this case, contact their support team, and they should be able to resend these details to your email.

Sometimes, you see the "Activation limit reached" error. This happens after you use multiple devices to use the 4K Video Downloader product. It supports up to 3 devices, so if you are experiencing this error on 4th or more devices, you need to purchase a new license key.

If you see the activation error, it might be because you entered the wrong license number. The company offers many products, and you may have bought a couple of them. So, make sure to enter the correct license key you used to purchase the video downloader.

Other common 4K Video Downloader activation errors are "Empty response" and "Invalid key."

Both of these errors pop up if you type the wrong license key, use an antivirus or VPN, or experience a network problem. To fix this, turn off the antivirus and VPN, connect to a different network, and then type in the key manually.

Part 3. Why Can't 4K Video Downloader Download From My Video Link?

Here are the most common reasons why the download error (with the red triangle) shows up on 4K Video Downloader:

• The operating system is denying the destination you are trying to save the video file.
• Your device is running out of storage.

• Your network is experiencing problems. Resolve this and if this fails, switch to another Wi-Fi.

Part 4. How To Fix 4K Video Downloader Error Failed to Download?

You've discovered the reasons for the download errors associated with the 4K Video Downloader. Now, here are the solutions:

Change Download Path

The first fix for the 4K Video Downloader download errors is simply to change the path where you want to save the video. This workaround has worked for many users.

Free Up Device Storage

Check the storage on your computer or Android. If running low, uninstall unnecessary media files and apps to free up space for the videos you want to download from the 4K Video Downloader. Also, run the Windows Disk Cleanup utility on your Windows PC to clear more space.

Enable Proxy In 4K Video Downloader

You can change your IP and location by enabling Proxy in 4K Video Downloader and bypass the location restriction causing the download error on YouTube links:

1. Get a free proxy server from a reputable online source.
2. Open the 4K Video Downloader app and click "Tools."
3. Next, head to "Preferences" > "Connections," and enable the "Proxy" option.
4. Select a protocol, and then type in your proxy server IP address, port, login, and password.
5. Save these settings and try downloading YouTube videos again.

Check Network Connection

Make sure you are getting enough speed on your internet connection. If not, restart your router. You can also try to use the device running the 4K Video Downloader closer to the router to resolve poor Wi-Fi signal strength. Alternatively, contact your ISP and ask them to resolve backend glitches. If none of this works, switch to another WiFi.

Part 5. Why Is 4K Video Downloader Not Parsing the Link?

4K Video Downloader parses the links to extract every information about the video before downloading it, like format, quality, etc. Sometimes, the app fails to read this information and gives you an error code.

Following are some of the reasons for the 4K Video Downloader parsing error:

• The Windows Firewall or the third-party antivirus is blocking 4K Video Downloader access to the internet to parse the video from the URL.
• 4K YouTube to MP3 not working? The app often throws the parsing error after YouTube updates its algorithms, and the 4K Video Downloader update is pending to address this issue.
• The video you are trying to download from a platform is set to private viewing.

Part 6. How to Fix 4K Video Downloader Parsing Error?

You now know the reasons for the "Can't parse this link" error while downloading from video URLs. Let's find a solution for each of them below:

Disable Windows Firewall and Antivirus

Windows Firewall is notoriously famous for blocking internet access and other permission for third-party apps like the 4K Video Downloader. That's why the app may fail to parse the video link. To fix this, switch off the Windows Defender Firewall while downloading videos.

Use Another Source

Downloading YouTube content in MP3 format is a popular feature of the 4K Video Downloader tool. If this feature is not working and you see the "Can't parse this link" error, update the app to the "+" version first. In case the error persists, try to find the same video on another streaming platform and paste its link into the app.

Use Public Video Links

Make sure that you are pasting the video link that is not set to private viewing. If you have uploaded the video to a streaming platform like YouTube, be sure to make it public first.

Part 7. Why Does the 4K Video Downloader Keep Crashing? 7 Reasons and Fixes

Are you trying to download videos using the 4K Video Downloader app, but it keeps crashing on your Android or desktop? Don't sweat; there are a few logical and technical reasons for this problem, and you can fix all of them in a few minutes.

Reason 1: Other apps or software are open in the background and consuming the necessary resources to run the 4K Video Download app on your PC or Android. To fix this, close all the memory-hogging apps running on your device and then relaunch the 4K Video Downloader app.

Reason 2: Your device software, whether Android or PC, can glitch due to a number of reasons and fail to run the apps. Instead of figuring them all out, shut down the device for a few minutes to give the OS a much-needed break and turn it on afterward. Hopefully, the 4K Video Downloader won't crash then.

Reason 3: It is possible that you may have failed to update the 4K Video Downloader app to the latest "+" version, and the bugs in the older version are causing this crashing issue. So, simply update this app on your device, and this will resolve the issue.

Reason 4: Like the outdated app, the old OS version of the device is equally responsible for app crashes. Therefore, always make sure that your device has the latest software to avoid these kinds of problems.

Reason 5: 4K Video Downloader files are corrupt, so you need to reinstall it.

Reason 6: If you are facing the 4K Video Downloader crash on your PC, the software system files might be corrupted. You may also experience this behavior while using other resource-intensive apps. To fix this, try a clean Windows OS reinstall and download the 4K Video Downloader again.

Reason 7: You might be downloading manually while selecting your desired downloading parameters on the 4K Video Downloader software or app. There's nothing wrong with this, but if you choose the wrong parameters, the app often crashes. It's a weird bug, but you can fix it by turning on the Smart Mode feature.
